摘要：
A posterior dynamics of an observed quantum particle in a quadratic potential is studied. It is proved that Belavkin's stochastic wave equation for the quantum particle with continuously observed 1) position, 2) momentum, 3) position and momentum is uniquely relaxing to the corresponding Gaussian wave packet for any initial square-integrable wave function. A comparison of the asymptotic position-momentum uncertainties of these measurements is given.
